Product Manager interview question
How do you plan a product launch?
A launch plan defines target users, positioning, readiness across product, support, legal and operations, migration and rollout stages, acquisition channels, success and guardrail metrics, monitoring, ownership, rollback and communication.

What a strong answer covers
How it works
A launch plan makes sure the product, the company, and the customers are ready at the same time. It defines the target users and the positioning, the message that tells them what changed and why it matters. Readiness spans product completeness, support training and help content, legal and privacy review, billing and operations, and the migration path for existing users. The rollout is staged, internal, beta, percentage, full, with success metrics and guardrails watched at each stage and a rollback that has been tried. Channels and timing for announcements are set, each workstream has an owner, and a launch review afterwards compares the plan with what happened.
Example
A new billing system launched in four stages over six weeks: internal accounts, 50 design partners, 10 percent of new customers, then all new customers with existing customers migrated by cohort. Support received training and macros two weeks ahead, legal approved the updated terms, the success metric was checkout completion with a guardrail on failed payments, and the rollback was a routing flag tested in staging. Stage three surfaced a tax edge case in one country that was fixed before the full rollout.
Common mistakes
- Treating launch day as the finish line rather than the start of measurement.
- Announcing to all customers before support has seen the feature.
- Launching without a rollback because the deploy is simple.
